As shown in fig. 2, in this embodiment, the water inlet pipe 2 is responsible for merging external rainwater and sewage and draining into the sewage intercepting and flow limiting well chamber 11, and the sewage draining outlet pipe 31 and the river outlet pipe 32, which are responsible for drainage, are respectively communicated and connected to the sewage system and the river. Meanwhile, the water inlet pipe 2 and the sewage outlet pipe 31 or the river channel outlet pipe 32 are crossed on the wall of the intercepting well, and are optimally vertically distributed, and the sewage outlet pipe 31 and the river channel outlet pipe 32 can be arranged on the same side or the opposite side of the intercepting well, and the arrangement positions of the sewage outlet pipe 31 and the river channel outlet pipe 32 correspond to the position of a sewage system and the position of a river channel. The diameter of the sewage discharging water outlet pipe 31 is smaller than that of the river channel water outlet pipe 32, so that rainwater can be discharged quickly when the water amount is large.
As shown in fig. 1, in this embodiment, in order to ensure that the river water does not flow back into the catch basin 1, when the river water level is within the range of the river water level a and the well water level b in the sewage interception and flow restriction well 11 is not lower than the river water level a, the hydraulic rotary weir gate 5 may be partially opened to drain the river water. When the water level rises too fast, in order to ensure that a large amount of water flowing into the intercepting well chamber 1 is not discharged into the sewage discharging and discharging pipe 31, the drainage water level c is taken as a limit, only the hydraulic rotary weir gate 5 is completely opened, and the flood running function is started.
As shown in fig. 1-2, a partition plate 13 is arranged between the sewage interception and flow-limiting well chamber 11 and the backflow prevention well chamber 12, and a reserved hole 14 matched with the hydraulic rotary weir gate 5 is arranged in the partition plate 13.

When the water level b in the well is low in dry seasons and early rains: after sewage and initial rainwater in upstream water enter the sewage intercepting and flow limiting well chamber 11 through the water inlet pipe 2, the hydraulic rotary weir gate 5 is closed, the electric flow limiting gate 61 is opened, and the sewage and the initial rainwater are completely intercepted to a sewage system through the sewage discharging and water discharging pipe 31 and are discharged to a sewage treatment plant.
When the water level of the inlet water continuously rises, the water level b in the 11 wells of the sewage interception flow-limiting well chamber reaches the water level which is greater than the water level at the position of the 5 weimen of the hydraulic rotating weir gate: the hydraulic rotary weir gate 5 is opened to open the flood-running function, the electric current-limiting gate 61 is partially opened and closed, and the cut-off part of the water body is discharged into the sewage discharge water outlet pipe 31.
When the water body received in the sewage interception and flow limitation well chamber 11 continuously rises to a level higher than the drainage water level c, the hydraulic rotary weir gate 5 is completely opened, the flood running function is started, the electric flow limitation gate 61 is closed at the same time, and the interception is not carried out, so that all the water body is completely discharged from the water outlet pipe 32 of the river channel into the river channel, and the forced drainage pump 4 is started to quickly discharge the water flow in the sewage interception and flow limitation well chamber 11 into the river channel through the anti-backflow well chamber 12, so that all the water body is completely discharged into the river channel.
